I have just bought a BDV-E290, which is a Blu-Ray player with surround sound. I would ideally like to use some existing Bose surround sound speakers that I have in place of the Sony speakers, but the BDV-E290 box uses non-standard connectors. Does anyone know where I can get connectors which will fit into the back of the BDV-E290 box and which I can attach some standard speaker cables to, which in turn will lead to the Bose speakers?
